Change in Airway Responsiveness After Allergen Exposure

Allergen Induced Increase in Indirect Non-allergic Bronchial Reactivity

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 11 (actual)
• Sponsor: University of Saskatchewan · Academic / Other
• Sex: All
• Age: 18 Years – 65 Years
• Healthy volunteers: Not accepted

Summary

Exposure to allergens changes the way the airway responds to some stimuli (methacholine). The investigators will look at whether or not exposure to allergens changes the way the airway responds to a different stimuli (mannitol) and compare that with the known stimuli (methacholine).

Conditions

• Allergic Asthma

Interventions

Type	Name	Description
DRUG	Mannitol	Indirect bronchoprovocation agent being compared to direct bronchoprovocation agent (methacholine)
DRUG	Methacholine Chloride	Direct bronchoprovocation agent being compared to indirect bronchoprovocation agent (mannitol)
